Question

The inner glandular layer of uterus is
A) Endometrium
B) Myometrium
C) Fallopian tubes
D) Perimetrium
E) Infundibulum

Answer 1

Hint: This layer does not consist of muscles and thus it does not bring about contractions and relaxations of the uterus. This secretes uterine milk that helps in implantation.

Complete Answer:
- Female reproductive system consists of a pair of ovaries, a pair of oviducts, uterus, cervix, vagina and external genitalia known as vulva.
- Uterus is the womb or hysteria, Implantation takes place inside the uterus.
- This is an important step as this marks the beginning of pregnancy.
- Reproduction can be seen in those females that are in their reproductive age.
- The beginning of menstrual cycle marks the beginning of reproductive age and this continues till the menopause.
- Menstrual cycle is an important cycle in the females that helps to prepare the uterus for implantation incase fertilization occurs.
- If fertilization does not occur, the uterus lining sheds and then reforms again.
- This cyclic change is known as Menstrual cycle.

Uterine lining: The uterus consists of three layers
(I) Perimetrium: This is the outermost layer that lines and protects the uterus
(II) Myometrium: The middle layer is made up of muscles (myo means muscles) that undergoes contraction and relaxation during parturition
(III) Endometrium: This is the innermost lining and this lining sheds every month and reforms to form the uterine lining. The zygote gets implanted in this layer and thus pregnancy begins. When zygote gets implanted, the secretions from endometrium help in its growth and development. Hence this layer is glandular.

Thus the question is about the inner glandular layer and hence the answer is Endometrium i.e. option A.

Option B is the middle layer
Option C is the oviduct. It is a part of female reproductive system
Option D is outermost layer of Uterus
Option E is part of Oviduct

Note: Endometrium is made up of two layers. These two layers are Stratum basale and stratum functionalis. Stratum basale is attached to myometrium while functionalis is towards the uterine cavity.
- During menstruation, only the stratum functionalis layer sheds while stratum basale remains intact.
